Dehydration From Colonoscopy Prep

A colonoscopy is a screening procedure where a camera is placed in the colon and pictures are taken. The procedure is an important part of early colorectal cancer detection, but it is an uncomfortable procedure that takes preparation. Dehydration is sometimes a result of colonoscopy preparation.

Colonoscopy Prep Procedure

Preparation for a colonoscopy involves taking a heavy dose of laxatives to clean out the colon and rectum, so that accurate pictures can be taken. These laxatives typically contain sodium phosphate.

Dehydration Causes

Sodium phosphate is known to cause dehydration. The excess bowel movements caused by laxatives also causes dehydration. The consumption of alcohol or carbonated drinks can worsen the dehydration.

Laxative Side Effects

The dehydration caused by sodium phosphate laxatives has been known to contribute to kidney damage. Other sodium phosphate laxative side effects can include abdominal pain and nausea.

Dehydration Prevention

Keeping a proper level of hydration before the preparation period and during the laxative stage, as well as after the procedure, is a huge factor in avoiding dehydration and any related side effects. Listen to your doctor’s recommendations on clear fluid intake.

Alternatives

Those who already suffer from health conditions that cause dehydration may be given a different form of laxative or preparation procedure.
